Limestone has been used throughout modern agricultural history for adding soil fertility. The purpose of liming your soil is to help increase the pH of the soil thus aiding in the uptake of nutrients and maximizing plant growth and crop yield. Garden Lime (also known as Agricultural Lime) is predominantly calcium carbonate, composed of the remains of ancient sea life which incorporated calcium into their shells thus leaving behind a pure calcium content. Large deposits of these sedimentary stones can be found around the world.
Agricultural Lime raises or sweetens and buffers the pH value in acidic soils, especially our Southeastern clay soils. Garden Lime helps to balance the availability of other nutrients while also adding the benefit of slowly released calcium. We recommend using Agricultural Lime for those needing pH adjustment and additional calcium, this is a welcome addition to the mineral makeup of most garden soils
A decrease in soil pH, know as soil acidification, is a natural process that is accelerated by crop production practices, especially the use of nitrogen (N) based fertilizers and heavy tillage. Soils with low pH levels, below 5.0, contain higher levels of available aluminum and manganese that can become toxic to plants an may inhibit growth and greatly reduce yields.Application Rates:
- 5-10 pounds per 100 ft2 of garden space
- 1/2 cup per cubic foot of potting soil
If you are applying lime in the fall, it is necessary to incorporate the lime into the soil to prevent surface runoff. Any crop that is pH sensitive should be limed in the fall prior to planting. Spring application is advantageous in areas where permanent sod is maintained, or where there are light applications vs heavy.
